Forget scrubs. Doctors need a dress code.

Clothing for physicians is more than just a matter of personal style: it is an emblem of their specialty, training and culture.

If you live near a hospital, you’ve probably seen the sight: a young physician in loose blue scrubs, standing in line at the grocery store. You can’t help but wonder if the young physician is lost. After all, it appears that he or she belongs in an emergency room – not the dairy section.

The oversized bottoms, dangling bright orange pajama knot, deep V-neck and beeper ensemble not only look out of place, but lead to a slew of thoughts. Is he coming from or going to a shift? Could her clothes carry some sort of hospital microbe? What detritus has the outfit picked up on public transit or in line at the ATM that will track back to an operating room or patient? Has the American trend toward casual attire gone too far?

Regardless of profession, we all play out the sartorial ritual of considering colors, textures, and garments for work, school and play.

Clothing for doctors is more than just a matter of personal style: it is an emblem of their specialty, training and culture.

Making a good first impression

In some cases, a physician’s attire is functional. A surgeon’s scrubs protect regular clothes from stains and patients from infection.

Sometimes, it’s about creating a good first impression and projecting the more professional, conservative image often associated with medicine.

Go to a doctor’s office, for instance, and you’re more likely to find physicians donning a shirt and tie, or jacket and blouse when interacting with their patients. In almost all of these cases, the emblematic uniform of physicians – the white coat – is present.

This month, about 20,000 newly minted physicians will enter residency programs across America, to begin their professional journeys. Each will care for and influence the lives of countless patients.

And each has been trained to avoid “anchoring bias,” or to not to take the first thing they learn about a patient as the most important, lest they reach a biased conclusion or incorrect diagnosis. Yet few doctors or medical students consider the first impression they make on patients. And clothes have a lot to do with that.

In an informal survey in our hospital, only two out of 30 medical students said that they actually thought about their dress when caring for hospitalized patients. Yet, over half of the medical students we spoke to agreed that what they wear is likely to influence patient opinions about their doctors. This illustrates a larger discrepancy between what doctors ought to wear and what they do wear – one that may arise from competing concerns or lack of guidance.

Just like the treatment doctors provide, that guidance should be grounded in evidence. For instance, a special report from infection-prevention experts found little evidence that germs on male doctors’ neckties, long sleeves, or white coats actually spread infections in a nonsurgical setting. So bans on such garments, such as those in place in some countries, may go too far.

Patients really like white coats

We recently published a study reviewing all available evidence regarding patient preferences for physician attire. We examined more than 30 studies that evaluated how patients viewed physicians’ attire.

In 21 of those studies, we found that patients had strong preferences about what physicians wore. And it looks like patients more often prefer for their doctors to wear formal clothing and white lab coats than not. Indeed, in 18 of the studies we reviewed, patients had a preference or positive association with this style of attire.

But as we reviewed these studies, three keys themes that suggest important variations in what patients may prefer their doctors to wear emerged. First, studies involving older patients or those from Europe or Asia all reported higher satisfaction when physicians wore formal attire.

Second, in emergency, surgical or intensive care settings, scrubs were not only preferred by patients, but also more often equated with professionalism. This makes sense, as in these more “hands-on,” procedure-oriented settings, formal suits, shirts and ties clearly seem out of place.

Finally, in doctors’ offices and outpatient clinics, scrubs were viewed unfavorably and often resulted in negative impressions.

Thus, from the patient’s perspective, a “one size fits all” approach may not work for doctor attire. Rather, the context in which a patient interacts with their doctor influences what they expect to see.

Given the tension between infection risk and patient preferences, it is not surprising that disagreement about dress code also exists among physicians.

After our study came out, the medical news Web site MedPage Today reported results from an informal, but still telling, online survey of over 2,000 patients and physicians about the “best approach to dressing for patient encounters.”

About 30 percent of doctors polled stated that they preferred to wear scrubs, casual attire or had no particular preference when caring for patients. However, more than 60 percent stated that doctors should wear white coats.

The online comments differed widely, with some physicians defiant in stating that they had “never worn a white coat in 30 years,” while others proclaimed, “priests and judges have their robes, we have our white coats.”

And despite clear patient preferences about what doctors wear while working, even the top-ranked hospitals in the nation, only a handful offer formal guidance on attire. Many vaguely recommend that clothes be “professional,” but without defining what professional means?

A dress code for docs?

How, then, should doctors dress when caring for patients? Clearly, more evidence is needed to guide members of the medical community. So we have launched a large study that aims to better understand what patients prefer when it comes to physician attire.

We plan to survey thousands of patients from the U.S., Italy, Switzerland and Japan in settings that span outpatient clinics, doctors offices and hospitals. Because generational effects and familiarity matter, we will specifically assess how factors such as age or how often a person interacts with the health system shape patient opinions.

While we collect data for this study, what best practices can we recommend in the interim, especially those 20,000 brand new residents?

When in doubt, formal attire with long-sleeved shirts and ties for men, and business attire for women, should prevail in non-emergency or non-operative settings.

This practice should hold true not just for weekdays, but also when physicians are working weekends and after typical business hours. Patients and their expectations remain unchanged, regardless of hour or day.

While scrubs are appropriate for operating or emergency rooms, we suggest changing into more formal attire to visit patients in the hospital or the clinic. Regardless of the occasion, flip-flops, showy jewelry or jeans simply don’t belong in the hospital, just as scrubs do not belong outside the hospital environment. Especially not in the grocery store.
